Application filed December 18, 1919. Serial No. 345,765.

scrubbing material to the face of the brush and second, to afford facilities for changing the scrubbing material.

I attain these objects by the means illustrated in the accompanying drawings in which- 7 Figure 1 is a top view of the brush. Fig. 2 is a view showing the bottom of the brush with the scrubbing material removed. Fig. 3' is a side view showing the scrubbing material clamped to thelbrush, while the dotted lines show the clamping wires and handle open for changing the scrubbing material. Fig. 4 is a view in perspective showing the clamp and handle. Fig. 5 is a sectional view on line 5-5 Fig. 1. Fig. 6 is a perspective view of the band for securing the outer edge of the scrubbing material to the rim of the brush.

Similar letters refer to similar parts throughout the several views.

A- is the back or holder part of the brush and is provided with grooves z' and 7'- extending lengthwise along its face. These grooves terminate at the ends in slots e-f-gand -71.. The holder is provided with a flange pwhich extends around its outer rim. In the holder near one end is a hole in which a fastener n having a beveled head (see dotted lines Fig. 3,) is adapted to turn.

B is the handle in one end of which is a slot-oadapted to receive fastener n-. G is a wire clamp to secure steel-wool pad D to the face of the holder. The end o is adapted to loop over the end of the holder at :c in slots -e and f-, pass over the steel-wool pad D and through slots -g and h' where it is secured to each end of pin u which is fulcrumed in hole 7::

in the end of handle B. When handle B is brought flush with the back of holder A and secured by fastener -n being turned 1n slot 0 it serves as a lever (the corner belng beveled at -z) to draw the wire clamp G into grooves -z' and j embedding a part. of the scrubbing material therein as shown in sectional view Fig. 5. E 1s a band to secure the outer edge of the scrubbing. material to the rim of the brush and is provided with a flange s which extends at an angle to facilitate pressing the band on thebrush over the scrubbing material. A groove g is provided in band E to receive a spring r which holds the ends of the band in proper alinement and presses it to the rim of the brush.

To change the scrubbing material fastener nis turned so it will pass through slot -0 of, handle B which, with clamp C may be moved to the position shown in dotted lines Fig. 3. Band E is then removed which releases the scrubbing material and another supply of scrubbing material may be secured by reversing the operation.

.What I claim is:

1..A brush consisting of a back having grooves therein; a faceof scrubbing material, means to secure the scrubbing material to the face of the brush, means to embed part of the scrubbing material in the grooves and a band to secure the outer edge of the scrubbing material to the rim of the brush.

2. A brush consisting of a block provided with grooves therein; means to embed part of a scrubbing material in the grooves; a split band provided with a groove therein and a split wire spring embedded in said groove bridging the ends of the band to secure the outer edge of the scrubbing material to the rim of the brush.

3. A brush consisting of a back having grooves therein; a face composed of scrubbing material; wires to clamp said scrubbing material to said back; means to embed said scrubbing material and said wires in the grooves of said back, and a band to clamp the outer edge of the scrubbing material to the outer edge of the brush.

4. A brush consisting of a block provided with a shoulder extending around its outer rim, a face of scrubbing material, a split band to engage said scrubbing material and provided with a flange and having a groove a part of said stee1-vvoo1 and said Wires into adapted to receive a spring to secure the the grooves of said back.
